Definitions

  • the present invention relates to ceilings in buildings, specifically to a suspended ceiling system and to a ceiling tile for a suspended ceiling system.
  • Suspended ceiling systems are used in many different types of buildings e.g. to lower the ceiling, to provide sound dampening, to facilitate mounting of light sources and other building equipment and to provide an aesthetically pleasing interior ceiling.
  • Suspended ceiling systems are attached to a supporting structure of some sort, such as the ceiling structure of the building.
  • Suspended ceiling systems usually comprises a plurality of ceiling tiles and a supporting structure in form of a grid.
  • the grid comprises profiles which support the ceiling tiles.
  • the ceiling tiles may have sound-absorbing and/or sound-insulating properties in order to improve the acoustic environment of the room.
  • the tiles for instance, may be made of a compressed fibre material such as mineral wool and especially glass wool.
  • the profiles may also support various equipment such as lighting devices, ventilation equipment, inspection openings, detectors, cable trays, loudspeakers, signs, sprinklers etc.
  • the suspended ceiling system may be fitted with ventialtion fittings such as diffusers.
  • a diffuser replaces a ceiling tile in the grid and is supported by the grid of profiles.
  • the ceiling tiles in such an application does not need to be provided with any particular properties for facilitating ventilation or flow of air.
  • Ventilation is provided above the suspended ceiling system and the air flows through the suspended ceiling system into the space below.
  • the suspended ceiling system must allow a certain amount of air flow to be able to pass through it in order to achieve the desired and/or required ventilation performance.
  • the object of the present invention is to provide a ceiling tile and suspended ceiling system which alleviates some of the problems with prior art.
  • a ceiling tile for a suspended ceiling system comprising a grid of profiles for supporting the ceiling tile.
  • the ceiling tile comprises a front surface intended to face a room in an installed state of the ceiling tile and a plurality of spacer elements discretely distributed along a perimeter portion of the ceiling tile.
  • the plurality of spacer elements is configured for separation of the ceiling tile and the grid of profiles in a direction perpendicular to the front surface, such that an air passage is generated allowing air to pass from the space above the ceiling tile into the room or space below. This facilitates diffuse ventilation without having to provide the ceiling tile itself with any particular features such as ventilation holes or materials that lets air pass through it.
  • the ceiling tile may comprise two opposite edges each provided with a stepped profile comprising an upper tongue having a tongue surface configured to face an associated supporting surface on the grid of profiles.
  • the plurality of spacer elements being configured to separate the tongue surfaces and the associated supporting surface.
  • the stepped profile facilitates hiding the air passage that is formed by the spacing between the ceiling tile and the grid of profiles from view, providing an aesthetically pleasing ceiling tile.
  • the plurality of spacer elements is arranged on the front surface of the ceiling tile or a surface parallel thereto.
  • the plurality of spacer elements may be arranged on a side surface of the ceiling tile or a surface parallel thereto.
  • the plurality of spacer elements may further be configured for engagement with the grid of profiles for support of the ceiling tile.
  • the plurality of spacer elements may be configured for separation of the ceiling tile and the grid of profiles in a direction parallel to the front surface.
  • the spacer elements may thus provide not only vertical spacing but also horizontal/lateral spacing for providing a desired air passage between the ceiling tile and the grid of profiles.
  • the plurality of spacer elements may be formed separately from the ceiling tile.
  • the spacer elements being attachable to the ceiling tile.
  • the spacer elements may be attached to each other for instance by being arranged on a strip of material such as adhesive tape or similar, thus proving the desired spacing between the spacer elements.
  • Each spacer element may further comprise a body portion and an anchoring portion for attaching the body portion to the ceiling tile.
  • Each spacer element may in one embodiment comprise a body portion attached to the ceiling tile by means of an adhesive, such as glue or adhesive tape.
  • a suspended ceiling system provided comprising a grid of profiles and a ceiling tile according to the first aspect.
  • the suspended ceiling system facilitates providing diffuse ventilation through the ceiling system. Ventilation can thus be provided to the space above the suspended ceiling system, the ceiling system will then allow fresh air to pass through it effectively. No visible dedicated ventilation diffusers are needed in the ceiling system which provides a uniform appearance which is often desirable.
  • the grid of profiles may comprise profiles having an inverted T-shape with a web and laterally extending flanges.
  • the ceiling tile may be supported by the flanges via the plurality of spacer elements.
  • Fig 1 shows a ceiling tile 100 in a suspended ceiling system 200 comprising a grid of profiles 300 for supporting the ceiling tile 100.
  • the grid of profiles 300 is suspended from a supporting structure in the building to which it is mounted.

  • the anchoring portion 24 may be provided with threads or circumferential ribs for increasing the axial load capability of the connection between the anchoring portion 24 and the ceiling tile 100.
  • the spacer element 20 may further comprise a body portion 22 which is intended to abut against the rear surface 104 of the ceiling tile 100 and thus limit/define the protrusion of the anchoring portion 24 from the opposite surface, i.e. the tongue surface 114 or the front surface 102.
  • Figs 9 to 11 shows further embodiments of the ceiling system 200 and the spacer element 20 respectively.
  • the spacer element 20 is attached with the anchoring portion 24 extending laterally into the perimeter portion 106 of the ceiling tile 100. Any vertical force on the spacer element 20 from the ceiling tile 100 will thus not be transmitted in an axial direction of the anchoring portion 24, which is preferable in some applications.
  • the spacer element 20 could be arranged on a ceiling tile 100 with a stepped profile 110 such that the body portion 22 of the spacer element 20 abuts against the tongue surface 114.
  • the anchoring portion 24 can thus be relieved of some or all of the vertical forces that arise from the ceiling tile 100 interaction with the grid of profiles 300.
  • the spacer element 20 is attached to the side surface 116 of the ceiling tile 100 such that it not only creates a vertical spacing between the ceiling tile 100 and the lateral flanges 302 of grid of profiles 300 but also a lateral or horizontal spacing between the ceiling tile 100 and the web 304 of the grid of profiles 300.
  • This is beneficial as it provides a ceiling system 200 in which both the desired vertical as well as the desired lateral spacing is automatically created during mounting of the ceiling tile 100 to the grid of profiles 300.
  • a ceiling tile 100 with a stepped profile 110 which is beneficial as the interface between the ceiling tile 100 and the grid of profiles 300 can be hidden.
  • the spacer element 20 also could be used with a ceiling tile 100 without a stepped profile 110, wherein the spacer element 20 is attached such that it extends below the front surface 102 of the ceiling tile 100 instead of below the tongue surface 114 as in Fig. 10 .
  • Fig. 11 shows another embodiment of the spacer element 20 configured for lateral attachment to the ceiling tile 100.
  • the spacer element 20 comprises one body portion 22 and two anchoring portions 24 for increasing the vertical load that can be placed on the body portion 22.
